Meet Enigmacursor: New dinosaur species unveiled at London's Natural History Museum
The Enigmacursor mollyborthwickae was a nimble, plant-eating dinosaur that roamed western North America around 150 million years ago, during the late Jurassic period.
Despite living among prehistoric heavyweights like Stegosaurus and Diplodocus, this little runner likely darted between their feet. Its fossil was initially misidentified as a "nanosaurus" - a murky name dating back to the 1870s - until closer analysis revealed it as an entirely new species.
Named for its puzzling classification history ('Enigma') and its long-legged agility ('cursor'), the Enigmacursor helps bridge a key evolutionary gap between early ornithischians and their larger, weirder relatives like Stegosaurus and Triceratops.
A skeleton of the Enigmacursor is now on display at the Natural History Museum, with full research published in Royal Society Open Science.

What is the Jurassic period and why did it end?
The heyday of dinosaurs, the Jurassic era saw Earth's climate change from hot and dry to humid and subtropical. The Jurassic period was characterized by a warm, wet climate that gave rise to lush vegetation and abundant life. Many new dinosaurs emerged—in great numbers. Above, Dimorphodon reptiles fly over a herd of Mamenchisaurus dinosaurs coming down to a river for a drink. Illustration by CoreyFord, Getty Images By National Geographic Staff Thanks to this rich record, we know that the Jurassic was the height of dinosaurs roaming a tropical Earth filled with ferns, flowering plants, and conifers. It was also a time when sea monsters, sharks, and blood-red plankton filled inland seas borne of crumbling landmasses. Here's what the Jurassic period was really like. ('Jaw-dropping' fossil reveals epic prehistoric battle) Environmental conditions during the Jurassic At the start of the Jurassic era, the breakup of the supercontinent Pangaea continued and accelerated. Laurasia, the northern hemisphere, broke up into North America and Eurasia. Gondwana, the southern half, began to break up by the middle Jurassic. (In 250 million years, this may be the only continent on Earth) The eastern portion—Antarctica, Madagascar, India, and Australia—split from the western half, Africa and South America. New oceans flooded the spaces in between. Mountains rose on the seafloor, pushing sea levels higher and onto the continents. All this water gave the previously hot and dry climate a humid and drippy subtropical feel. Dry deserts slowly took on a greener hue. Palm tree-like cycads were abundant, as were conifers such as araucaria and pines. ('Living fossil' cycad plants are actually evolution's comeback kings) Ginkgoes carpeted the mid- to high northern latitudes, and podocarps, a type of conifer, were particularly successful south of the Equator. Tree ferns were also present. (Huge fossil is oldest giant flowering tree in North America) The oceans, especially the newly formed shallow interior seas, teemed with diverse and abundant life. At the top of the food chain were the long-necked and paddle-finned plesiosaurs, giant marine crocodiles, sharks, and rays. Fishlike ichthyosaurs, squidlike cephalopods, and coil-shelled ammonites were abundant. Coral reefs grew in the warm waters, and sponges, snails, and mollusks flourished. Microscopic, free-floating plankton proliferated and may have turned parts of the ocean red. (See the microscopic world of plankton in stunning detail) Dinosaurs flourished during the Jurassic period. Species such as Harpactognathus, Camarasaurus, Ceratosaurus, Allosaurus, Camptosaurus, Marshosaurus, and Megalneusaurus (illustrated above) quickly dominated the world. Illustration by Sergey Krasovskiy,Jurassic period dinosaurs On land, dinosaurs were making their mark in a big way—literally. The plant-eating sauropod Brachiosaurus stood up to 52 feet (16 meters) tall, stretched some 85 feet (26 meters) long, and weighed more than 80 tons. (How the world's deadliest mass extinction actually helped the rise of dinosaurs) Diplodocus, another sauropod, was 90 feet (27 meters) long. These dinosaurs' sheer size may have deterred attack from Allosaurus, a bulky, meat-eating dinosaur that walked on two powerful legs. This story originally published on January 6, 2017.

'Alien: Earth' might just be my favorite show of all time — and it proves the franchise is thriving
Hearing we were getting a TV show set in the 'Alien' franchise had me a little worried at first. As a superfan, I've always found the iconic sci-fi horror movies incredibly effective, especially in how much terror they pack into just 90 minutes of claustrophobic space. So, the idea of stretching that into eight hours of content definitely gave me some concerns. But now, having seen the first six episodes, I can confidently say I'm genuinely blown away. I'll admit some of my opinion might be a little biased, but I tried to distance my love for the franchise and be critical of 'Alien: Earth' fairly. Even then, it still blew me away. 'Alien: Earth' is pure sci-fi goodness, wrapped in a smart TV show format that's equal parts character drama and savage horror. There's so much to appreciate here, and showrunner Noah Hawley exceeded all expectations. He clearly knows the franchise inside and out, delivering exactly what fans want from an 'Alien' series. With a flashy marketing campaign (including an exhibit at the Natural History Museum in London) Disney and Hulu clearly want 'Alien: Earth' to be the next big TV event. And I'm not alone in thinking this: my colleague Rory Mellon called it the best new show of the year in his review. Now that 'Alien: Earth' is streaming its first two episodes on Hulu (and Disney Plus in the U.K.), I just have to talk about why it might rank as my No. 1 show of all time, and why you need to stream it right now. Most of the 'Alien' movies follow a group of human characters (plus an android) who come face-to-face with the Xenomorp, with each of them dying one by one until only the final girl remains. 'Alien: Romulus' leans heavily on this concept, and while I still love this format (and wouldn't mind seeing it used in future 'Alien' movies), I'm glad 'Alien: Earth' breaks away from it. Don't get me wrong, in the first two episodes we follow a group of search and rescue soldiers who encounter the Xenomorph aboard the Weyland wreckage (and soon discover exactly what they're up against). Episode 5 takes that format almost entirely, feeling like a 60-minute 'Alien' movie, which was incredible. But for the most part, the series breaks that mold in a really smart way. Get instant access to breaking news, the hottest reviews, great deals and helpful tips. That comes down to its storytelling structure and how Hawley clearly wanted to explore the concept of 'man is the monster' even further. Instead of following characters' traumatic survival on a spaceship, we're introduced to Prodigy, a major Earth-based corporation that, in 2120, is one of five companies governing the planet. Prodigy is another example of corporate greed, led by the ego-inflated, shoe-hating CEO Boy Kavalier, who is very unlikeable (Samuel Blenkin delivers one of the strongest performances). After learning about the Weyland research vessel crashing into his city, he becomes determined to obtain everything on that ship including every species that was caged on board. 'Alien: Earth' strays from the usual movie format by introducing multiple species and showing how organizations like Prodigy constantly hunt for the next big innovation. Instead of characters dying one by one, the group of hybrids in 'Earth' must survive the very organization that created them. Unfortunately, in the process, they encounter several species (and the deadly Xenomorph) under far from ideal circumstances. In essence, 'Alien: Earth' expands the franchise's storytelling from a simple survival horror into a deeper, more layered drama about corporate power, scientific experimentation, and diverse alien threats. It's a remarkable piece of TV. I think any 'Alien' fan will agree that the franchise has always been visually stunning. Even the clean aesthetic of 'Prometheus' was pleasing to look at, alongside the grittiness of 'Romulus' and the rough, gritty look of 'Alien 3' (despite some dodgy special effects). 'Alien: Earth' takes all these elements and meshes them together. We experience the claustrophobic terror of spaceship corridors, the sleek corporate design of scientific labs inside Prodigy's main building, and the fresh addition of the natural setting at the Neverland research facility, which is something new for the franchise. From the very first scene in episode one, it nails the vibe. You could probably guess it's 'Alien' even if you closed your eyes and listened to the sound alone, including the iconic clicking of the computer interface. Every aspect of the TV show screams 'Alien' and I found myself almost jumping with excitement when something recognizable pops up. The set design, haunting music, and satisfying opening title sequences only add to the quality of this incredible series. Most of all, I had so much fun watching 'Alien: Earth,' and I was sad every time an episode ended. Franchise fans will eat it up, and even those who haven't encountered any piece of 'Alien' media can still enjoy this show with no prior knowledge. Hawley does an incredible job setting up the story and characters without relying on lore from the movies. Plus, even though we see 'more Xenomorph on screen,' the design is still incredible. I'm glad they stuck with practical effects for the costumes, especially since other species required special effects. The Xenomorph looks as cool as ever with its flashy silver fangs and dripping drool, and horror fans will especially love how gory things get. This show actually has some pretty shocking scenes, to say the least. Based on the first six episodes, I could easily say 'Alien: Earth' is my favorite show of all time. Maybe. 'The Walking Dead' has been my top show for years and one I've rewatched the most, so it's hard to say anything could truly top that. But 'Alien: Earth' is definitely giving it a run for its money. In fact, I'd fight a Xenomorph barehanded to experience this sci-fi masterpiece again for the first time. The first two episodes of "Alien: Earth" are now streaming on Hulu in the U.S and Disney Plus in the U.K.

Perseid meteor shower nears its 2025 peak, but viewing might be 'hampered'
It's that time of year again, and the peak of what's revered as the 'best meteor shower of the year' is approaching. The Perseid meteor shower is considered the best of the year due to how many meteors viewers can see, about 50 to 100 per hour, according to NASA. Meteor showers occur when Earth passes through streams of debris left behind by comets and asteroids, according to the Natural History Museum in London. A meteor shower peak occurs when Earth passes through the thickest part of the debris stream; that's when viewers see the highest rate of meteors. Here's more on the Perseids, how to check them out, and why this year's display could be diminished. When is the Perseid meteor shower? While the Perseid meteor shower is active from July 17 to Aug. 23, the peak is between Aug. 12 and 13 during pre-dawn hours, NASA said. It may be possible to see meteors from the shower as early as 10 p.m. though, according to NASA. Why this year's Perseid shower might be 'hampered' During this year's peak on Aug. 12, the Perseid meteor shower may be "hampered" due to an 84%-full moon, NASA said. "Unfortunately, this year the Moon is nearly full on the peak night, and its glare will wash out all but the brightest meteors," NASA wrote. 'A few bright meteors may still be seen in the pre-dawn hours, but viewing conditions are not ideal,' NASA wrote, adding that skywatchers could look forward to another favorite meteor shower, the Geminids, which is set for "moon-free viewing in December." Sky condition, or the average amount of the sky covered with thick clouds, also plays a role in how well viewers can see the meteor shower. The night of Tuesday, Aug. 12, sky cover will be higher in southeastern U.S. states such as Georgia and North Carolina. Gray areas on the below map are expected to have higher sky cover in the early morning hours of Tuesday, Aug. 12, according to a National Weater Service forecast posted Aug. 8. How to see the Perseid meteor shower According to NASA, some tips for seeing meteor showers include: Perseid meteor shower has bright lights, fireballs The Perseid meteor shower peaks in mid-August each year, NASA said, giving viewers the chance to peer at bright meteors that leave long "wakes" of light and color behind them as they move through the Earth's atmosphere. Perseids are also known for fireballs, or larger explosions of light and color that can last longer than the average meteor streak and are brighter, NASA said. The meteor shower moves at the fast rate of 37 miles per second or 133,200 miles per hour, according to the American Meteor Society (AMS). Where did the Perseid meteor shower get its name? The meteors are called Perseids since they come from the part of the sky near the constellation of Perseus, named after the Greek hero, the AMS said. 'The constellation for which a meteor shower is named only serves to aid viewers in determining which shower they are viewing on a given night,' NASA said about the name. 'The constellation is not the source of the meteors.' The Perseids are particles released from comet 109P/Swift-Tuttle as it returns to the inner solar system, the organizations said. Comet Swift-Tuttle takes 133 years to orbit the Sun once, and it last visited the inner solar system in 1992. Saleen Martin is a reporter on USA TODAY's NOW team.
